What have you learned from the obstacles you’ve faced and how will this knowledge help you succeed in college?

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.

explanation:

the teacher i would like to have must be a kind, caring and understandable teacher. she should be interactive with us and always plan fun activities to in our studies. she should be a teacher who would correct our mistakes when we do something wrong and guide us if we are weak. she should always be strict if we do something bad but must be praising us when we do something good. she she not take any as her favorite in her class but take everyone as her favorite.

(i hope this will u if there is something send me a reply)

hey there,

your answer is a) today we hope for clear skies.

let's look at the word(s) progressive verb. progressive means its happening right now. it is not going to happen and it has not already happened. it is happening right now. the sentence "today we hope" in option a is an example of a progressing verb. they are hoping right now. options b, c and d are not progressing verbs. they contain the words have, roared and will be. those words tell us that it has either happened or will happen. a is your answer.

best of luck,

- i.a. -

the second sentance should look more like this: the doughnuts we bought were the best we had ever tasted.
